  • Adhesion to numerous substrates, such as granite, composite stones, ceramic tiles, brickwork, metals, plastics also compatible with copper.
  • Low modulus (conforms to ISO 11600 F&G 25 LM).
  • Movement capability up to 50% (ASTM C920 class 50).
  • Non-staining (ISO 16938-1, ASTM C 1248).
  • Sealing joints in premier bathrooms & kitchens.
  • Glass to glass joints.
  • Sealing glass to metal.
  • Expansion joints in brickwork/stonework.

Joint dimensions

The minimum joint size suggested is 5mm x 5mm for internal use and external use 10mm x 8 mm (width x depth). Maximum recommend width of the joint is 30mm x 30mm, but the joint depth should be roughly half the joint width for the ideal seal.


After applying the sealant, it can be smoothed in the joint with water or with a neutral, non-staining water-based smoothing agent and a suitable tool (e.g., Bond-It Applicator Kit). Smoothing the sealant isn’t just recommended for aesthetic reasons, but it will assist in the bonding of the sealant to the substrate.
